Hello Kingdom Builders, The Steam Spring Sale is just around the corner—have you all prepared your wallets? Wait, hold on… I’m getting ready to go on a shopping spree too! But if everyone is busy buying The Witcher 3 for $3.99, who’s going to buy ours? 🤔 Originally, we planned to launch Kingdom of Cards before the Spring Sale, hoping to catch everyone while their wallets were still “well-stocked.” But thanks to a friendly heads-up from Steam (big ❤️ to Valve), we realized that launching at that time might affect the game's visibility. So, we’ve decided to make a slight adjustment—the game will now launch on

March 24 at 3:00 AM (PDT)!
